教師:不同的時代造就了不同風格和不同精神內(nèi)容的詩詞,請同學們回顧必修一和必修二兩宋中央集權(quán)的加強和經(jīng)濟的發(fā)展狀況。學生:回憶回答。教師:請同學們結(jié)合時代背景和詞的特點理解詞為什么能夠成為宋代文學的主流形式和標志?學生:兩宋時經(jīng)濟重心轉(zhuǎn)移到了南方,商業(yè)發(fā)展打破了時間和空間的限制,城市繁榮,市民數(shù)量不斷增加。詞的句子長短不齊,便于抒發(fā)感情,并且能夠歌唱,更能適應市井生活的需要。于是,詞成為宋代文學的主流形式和標志。教師:宋代文人地位提高,宋詞就是一個個時代的畫卷:大宋的悲歡離合都寫在了里面。除了詞之外,宋代民間還興起了一種新的詩歌形式,即散曲。學生:回答散曲的發(fā)展階段及特點、元曲的含義、特點。教師:在中國古代詩歌輝煌發(fā)展的同時,也產(chǎn)生了供人們閑來無事消遣的小說。
明確:(1)結(jié)繩記事說。原始記事的一種方法。人類在沒有發(fā)明文字或文字使用尚不普遍時,常用在繩索或類似物件上打結(jié)的方法記錄數(shù)字,表達某種意思,用以傳達信息,處理事件。 (2)書畫說。(3)倉頡造字說。中國自古就有倉頡造字之說。文字的發(fā)明是人類發(fā)展史上一件石破天驚的大事,它將人們的思維、語言、經(jīng)驗以及復雜的社會現(xiàn)象記錄下來,使文化得以傳播交流、世代傳承。2、漢字的形體:中華民族五千年的歷史中,漢字的演變,從甲骨文--金文--大篆--小篆--隸書--草書--楷書--行書,字形由象形到點橫豎撇捺的方塊字,經(jīng)歷了漫長的歲月。其中凝聚著民族的智慧,也體現(xiàn)出漢字逐步完善的過程,凸顯其方方正正、四平八穩(wěn)的特點。漢字又是一種文化的體現(xiàn),那些經(jīng)過藝術(shù)處理的漢字或跳起了拉丁舞、有的如同酒醉的成龍打起了醉拳,更是讓我們感到的是在欣賞漢字在紙張上跳舞,所以:書法是“紙上的舞蹈”。請大家看到書上的相關(guān)內(nèi)容,注意每一種形體的漢字的載體是什么,其功能又有什么不一樣。
請一位朗誦水平較好的學生,有感情的朗讀課文12自然段,其他同學完成一項任務(wù):這一段可否去掉?為什么?學生思考、圈畫、交流、討論,然后小組發(fā)言,其他小組補充,教師從旁予以點撥,引導學生進一步明確作者的思想情感。明確:作者要創(chuàng)造一種文化氛圍,于自然氣息之外再添一重文化氣息,與“故都”題旨暗合。從行文章法上看,這里是宕開文筆,縱橫議論,顯出深厚的文化底蘊和開闊的思路。這一段采用議論,通過古今中外的引證,說明感秋處處有,中國文人最突出,而秋“深味”非在中國北方莫屬,這其實還是為了突出故都之秋。(設(shè)計意圖:提高學生探究的能力,充分把握本文的教學內(nèi)容,深刻體悟作者的情感,了解作者對秋的禮贊情感,從而突破教學難點。)
5.5癌癥的預防作為本節(jié)最重要內(nèi)容,且與生活息息相關(guān),我采用老師引導、學生討論總結(jié)的方法進行教學。從生活各方面總結(jié)出保健良方 ,既對知識有很好應用,又體現(xiàn)對生命的熱愛。此時,本節(jié)課達到高潮,同學們意氣風發(fā),熱烈討論,實現(xiàn)本節(jié)課的教學目標。5.6 癌癥的治療通過講述癌癥治療方法的副作用,激發(fā)學生探究生物學欲望,激勵學生立志除癌。 在此,我選用一則關(guān)于一名癌癥晚期病人運用心理療法成功戰(zhàn)勝癌癥的故事,在于對不同層次的學生進行多方面啟發(fā)教育,體現(xiàn)面向全體學生的課程理念。5.7 愉悅總結(jié),及時反饋本節(jié)知識點零散,我將帶領(lǐng)學生回憶瀏覽本節(jié)內(nèi)容,使零散知識點系統(tǒng)化。在課堂反饋環(huán)節(jié),我通過簡單練習采用分組競答的方式把握學生對知識的掌握程度,并給予表現(xiàn)突出的學生適當獎勵,這是本節(jié)課第三個亮點。競答既使課堂顯得緊湊、集中,又有利于形成學生的競爭意識,還使得學生的知識得以鞏固應用。
4、最后從生物的壽命引入,探討細胞的死亡。強調(diào)細胞死亡有兩種形式。(1).細胞壞死,它是由某些外界因素造成細胞急速死亡,是一種被動性死亡;(2).細胞凋亡,這是一種由特定基因控制的主動性死亡。細胞壞死與細胞凋亡在形態(tài)學和生物化學上有著明顯的區(qū)別。細胞凋亡有廣泛的生物學意義,比如胚胎發(fā)育期手的發(fā)育如果沒有細胞的調(diào)亡就不會有纖細的手指;如果沒有正常的細胞調(diào)亡,蝌蚪的尾部就不會消失,它將永遠不能變成青蛙……。正常的細胞調(diào)亡還肩負著維持各種組織器官固有體積和形態(tài)的功能;還會使機體內(nèi)異常的細胞得到及時清除,去處潛在的隱患;例如癌癥就是異常的細胞沒有及時死亡的結(jié)果……。因此細胞的正常死亡是生物體的一種非常重要的調(diào)節(jié)機制,是機體平衡細胞增殖,調(diào)節(jié)機體細胞樹木恒定的方式,是必不可少的生命過程。(15分鐘)5、課堂小結(jié),可以把課堂傳授的知識盡快地轉(zhuǎn)化為學生的素質(zhì);簡單扼要的課堂小結(jié),可使學生更深刻地理解政治理論在實際生活中的應用,并且逐漸地培養(yǎng)學生具有良好的個性。
設(shè)問:DNA復制后兩個子代DNA分子與親代DNA分子是否完全相同?為什么?通過設(shè)問,讓學生進一步理解和鞏固DNA復制的全過程。接下來讓學生總結(jié)出DNA復制的四大基本條件:① 模板:開始解旋的DNA分子的兩條單鏈;② 原料:是游離在核液中的脫氧核苷酸;③ 能量:是通過水解ATP提供;④ 酶:酶是指一個酶系統(tǒng),不僅僅是指一種解旋酶。最后通過以上分析,總結(jié)出DNA復制的意義以及在生活中的應用:意義:DNA通過復制,使遺傳信息從親代傳給子代,從而保證了物種的相對穩(wěn)定性,保持了遺傳信息的連續(xù)性,使物種得以延續(xù)。應用:目前DNA分子廣泛應用于刑事案件偵破等方面:如:DNA分子是親子鑒定的主要證據(jù)之一。把案犯在現(xiàn)場留下的毛發(fā)、血等進行分析作為破案的證據(jù),與DNA有關(guān)。五、設(shè)計課堂練習:設(shè)計一題典型課堂練習:即有關(guān)半保留復制及計算的習題:
3、遺傳密碼的特點 連續(xù)性、簡并性、通用性5、課堂練習6、作業(yè)布置假如,我們利用(ACU)n核苷酸長鏈合成了含有蘇氨酸的多肽,那么蘇氨酸可能的密碼子有哪些?如何運用實驗方法確證蘇氨酸的密碼子究竟是什么?七、教學反思1、教材中豐富的科學史料,是我們在課堂上進行探究性學習活動的良好素材,教師要整理和運用好。千萬不要低估學生的思維能力,當學生的思維能力被你想方設(shè)法激發(fā)出來的時候,你會發(fā)現(xiàn)他們的創(chuàng)造力是無窮的。2、探究性學習的目的并不僅僅是問題的解決,更重要的是在探究過程中體驗和獲取科學研究方法,培養(yǎng)合作與分享的精神以及實事求是的科學態(tài)度,鍛煉思維能力,提高科學素養(yǎng)。3、學生是學習的主體,教師是引導者。我們要采取措施讓學生積極主動地參與到學習活動中來,通過他們的思考、討論、爭辯、合作等活動來獲取方法,建構(gòu)知識。
(一)教材的地位與作用該節(jié)教材以水資源作為案例,說明在不同的生產(chǎn)力條件下,水資源的數(shù)量和質(zhì)量對人類生存和發(fā)展的意義。教材首先從水資源的概念入手,介紹世界和我國的水資源的狀況,接著辨證論述水資源與人類社會之間的相互影響,緊扣水資源的數(shù)量和質(zhì)量隨時空變換,對人類生存與發(fā)展的影響,科技對水資源的利用也發(fā)揮了一定作用,但是隨著人口持續(xù)增長、經(jīng)濟高速發(fā)展,不能從根本上解決水資源的短缺,因此必須要從開源和節(jié)流兩方面合理利用水資源。此部分內(nèi)容穿插圖片和實例,特別是通過以色列水資源的利用和咸海面積縮小的兩個案例,讓學生明確和鞏固以上觀點。(二)教學目標(1)知識與技能目標:1.通過讀圖分析數(shù)據(jù)明了水資源的概念。2.結(jié)合事例了解水資源對人類發(fā)展的意義。3.通過分析圖表資料認識全球和我國的水資源狀況,提高讀圖分析能力。4.以我國為例,針對我國的水資源利用狀況,結(jié)合所學,學生合作探究我國水資源合理利用方案,進而歸納基本的水資源可持續(xù)利用策略和措施。
一、說教材本節(jié)課選自于人教版語文必修二第二單元詩三首中的一首詩歌,它是陶淵明歸隱后的作品。寫的是田園之樂,實際表明的是作者不愿與世俗同流合污的心聲,甘愿守著自己的拙志回歸田園。學習該詩,有助于學生了解山水田園詩的特點,感受者作者不同流俗的高尚情操,同時可以培養(yǎng)學生初步的鑒賞古典詩歌的能力。
(一)教材的地位新中國的成立是20世紀的一件大事。它結(jié)束了幾千年封建專制統(tǒng)治的歷史,開啟了中華民族發(fā)展的新紀元。本課側(cè)重這一時期一個非常顯著的特征,即制度的更新,它本身具有知識的延續(xù)性和鋪墊性。新中國的成立促進了社會經(jīng)濟的發(fā)展,也為祖國的統(tǒng)一奠定了重要基礎(chǔ)。(二)教學目標依據(jù)新課程以人為本,促進學生全面發(fā)展的要求,同時,針對高一年級學生具備一定基礎(chǔ)知識但掌握不牢固,對歷史興趣濃厚但又自制能力差的特點,我對本課的三維目標設(shè)定如下:見多媒體。(三)教學重點的確定及處理本課的主題是新中國的民主政治建設(shè),這個問題的掌握對以后學習中國民主政治建設(shè)的進程有很大幫助,并且學生能力的提高也有賴于對它的認識,所以確定“人民代表大會制度的創(chuàng)立”是教學重點。
二、君主專制的演進(即中央政治制度的演變)通過地方政治制度演變的學習,掌握方法以后,以學生歸納整理基本線索為主,教師適當點撥,注意糾錯。1. 漢承秦制,又有所變化。教師點撥強調(diào)繼承與發(fā)展兩個方面。創(chuàng)設(shè)情景:同學們看了電視連續(xù)劇《漢武大帝》后,知道漢武帝劉徹在繼位之后,就急于對西漢王朝的政治制度進行改革。那么,西漢初期中央政治制度的基本框架是怎樣的呢?漢武帝為什么要對它進行改革呢?改革后的西漢中央集權(quán)制度又是怎樣的呢?請大家議一議,想一想。主干知識:西漢初期的中央政治制度的最大特點是“漢承秦制”。具體表現(xiàn)在兩個方面:一是繼續(xù)實行皇帝制度,維護皇權(quán),這一做法也為后來各王朝所沿用;二是在中央設(shè)立三公,分別掌管行政、監(jiān)察和軍事。到漢武帝時,“中朝”成為西漢重要的中央決策機構(gòu),尚書令的權(quán)力日益重要,以丞相為首的三公九卿的權(quán)力被削弱,演化為執(zhí)行機構(gòu)。到了東漢光武帝時,進一步剝奪三公權(quán)限,擴大尚書的權(quán)力。
1789年法國大革命后,共和派與君主派之間進行了長期反復的斗爭,直到1875年法蘭西第三共和國憲法通過才最終確立了共和政體,它為法國資本主義的進一步發(fā)展奠定了基礎(chǔ)。專制色彩濃厚的普魯士通過王朝戰(zhàn)爭這種自上而下的形式,完成了德國的統(tǒng)一。1871年德意志帝國憲法頒布,德國君主立憲政體確立,保留了濃厚的專制殘余和軍國主義傳統(tǒng)。但資產(chǎn)階級代議制的建立使德國的資本主義工業(yè)迅速發(fā)展起來,19世紀末躋身到世界強國行列。資本主義政治制度擴展到了歐洲大陸,隨著這兩個國家資本主義政治制度的確立,近代西方主要資本主義政治制度得以最終確立。四、板書一、法國共和政體確立的艱難歷程1、艱難 (1)表現(xiàn) (2)原因2、確立標志:法蘭西第三共和國憲法
二、教學目標:(一)知識與能力:學生了解夏商周期的政治制度的內(nèi)容和特點,對不同的政治制度有一個較為全面的認識。在此基礎(chǔ)上,學生根據(jù)所學的知識,歸納和評價從夏到周政治發(fā)展的特點以及內(nèi)在規(guī)律。(二)過程與方法:在學習的過程中,采用小組合作討論的形式,讓學生學會與他人合作與溝通,提高自主探究的技能。(三)情感態(tài)度與價值觀:政治制度的不斷更新是古人制度創(chuàng)新的結(jié)果,而這種制度的不斷更新也推動文明的發(fā)展。這是古代先民的智慧結(jié)晶,學生要引以為豪。而通過本課的學習,可以增強學生們的民族自豪感。三、說教科書:本課作為高中歷史教材的開篇,是認識整個古代政治文明史的起點,具有統(tǒng)領(lǐng)和示范作用。本課總共有三個子目,主要講述了夏商周的政治制度。主要介紹了夏朝公共權(quán)力的出現(xiàn),分封制的內(nèi)容、分封的對象、 “以嫡長子繼承制為核心的宗法制度”介紹了宗法制的來源、內(nèi)容,以及禮樂制度的大致內(nèi)容。
Textbook: Senior English for China (Book 4), by Liu Daoyi Time Allotment: 1 period (40 minutes)Date: March 20, 2014Teaching aids: blackboard, Multi-media, Power Point, chalk I. Text Analysis (教材分析)This unit is about body language, and the text selected in the reading part demonstrates the difference and similarity of body language in many parts of the world. Through learning this passage, students are required to raise their awareness of using body language in different parts of the world. As body language is closely related to our daily life, it is easy to arouse students’ interest in learning this text. Reading skills and speaking training are designed around the text.II. Teaching Objectives (教學目標)By the end of the lesson, students will be able to:1. Language Skill Objective(語言技能目標): develop reading ability (skimming and scanning)as well as speaking ability.2. Cultural Knowledge Objective(文化知識目標): know about the cultural differences of using body language.3. Affective Objective(情感目標): increase students’ awareness of using body language correctly in different cultures. III.Teaching Focuses and Difficulties(教學重點和難點)1. Teaching Focuses(教學重點): the difference and similarity of body language in many parts of the world.2. Teaching Difficulties(教學難點): develop students’ reading abilities of skimming and scanning and ask the students to show their opinions with fluent English.
Good morning, distinguished judges:It’s my honor to talk about my teaching ideas with you. Today my topic is Women of Achievement. My presentation consists of six parts: the analysis of teaching material and student, teaching aims, key and difficult points, teaching and studying method, teaching procedures and blackboard design.First, let’s focus on the analysis of teaching material. This lesson is from New Senior English for China Student’s Book 4 Unit 1, the reading part. The main topic of the passage is the introduction of a student of Africanwildlife. After this lesson, the students will learn more information about her studying chimps in Africa, and their reading and speaking abilities can be developed as well.The next part is the analysis of students. My students are in senior high students. They have learnt English for many years, they’ve known many words and sentences, but their speaking and reading abilities are still not very good. So I will practice their speaking and reading abilities through different exercises.According to the New Standard Curriculum and the present situation, I set the teaching aims as follows: firstly, knowledge aims. Students can grasp some new words, such as worthwhile, move off. Moreover, students can understand the content of the passage and get familiar with the topic of studying chimps in wildlife. Secondly, ability aims. Students can use reading strategies such as skimming and scanning in reading process. Thirdly, emotional aims. Students can have the awareness of protecting animals and care about animals.Based on the above analysis, the key point of this lesson is to get the main idea and the detailed information from the passage; the difficult point is to talk about the wildlife protection and use reading strategies.
Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill
Knowledge objectives:(1) to make Ss grasp the usage of words, expressions and sentence structures: statistics, struggle, thanks to, rid of, some patterns for persuasion, the “ing” form as subject and object;(2)to use learnt knowledge to persuade sb.Ability objectives:(1) to develop Ss’ reading skills(skimming, scanning, word guessing);(2) to improve Ss’ speaking, communicating and cooperating skills.Emotional objectives:to make Ss know the contribution of Yuan,and learn his spirit and his simple life time.Teaching important and difficult points:(1) some words, expressions and sentence structures mentioned above;(2)the content of the text;(3)training their reading and speaking skills.Teaching methods: CLT, TBLT,QT.Learning strategies: CLS, QLS, TBLS.Teaching procedures:Step 1 lead-in: (1) teacher plays a piece of recent news from CCTV about the harvest of the super hybrid rice, and ask students whether they know Yuan or not, and talk about him and his contribution.(2)Brain storm: let Ss describe Yuan in their minds including his appearance, his living condition and so on.Step 2 fast reading tasks:(1)teacher introduces Yuan and super hybrid rice(2)make Ss read the text as fast as possible with questions.

通過寫文章梗概,培養(yǎng)學生綜合運用語言的能力,學習用恰當?shù)挠⒄Z描述科學家的故事。這是本課的教學難點。教師可以使用完形填空的方式來幫助學生整理語篇,從而來降低難度。本課的教學重點的突破方法是:在閱讀前,讓學生初步了解得出科學觀點所需要的基本程序,從而輕松而自然地導入文章的閱讀;在閱讀過程中,由易到難設(shè)計快速閱讀和精讀的問題,層層推進各種閱讀活動,讓學生對閱讀內(nèi)容從整體感知到細節(jié)理解,最后深層讀懂整篇文章,同時加強閱讀策略的指導,讓每個學生都主動參與課堂教學活動,最終達到提高閱讀能力的目的。Step 4 Post-readingGroup Activities四人小組共同合作,在老師的適當指導下,就以下2個問題展開討論,讓學生就所知、所學、所感和所想融入話題,然后抽若干同學代表作小組發(fā)言。1. What do you think about John Snow, and what should we learn from him?2. Cholera was 19th century disease, which two diseases are similar to cholera today? Why?
今天我們來介紹一下必修五第四單元的授課方式。這個單元的題目是Making the news。應該是學生比較感興趣的話題,學生往往對新聞工作充滿好奇,所以我們可以利用這個機會多設(shè)計一些師生互動和學生互動,來激發(fā)起學習的積極性,提高學習效率。同時我們可以利用這個單元不僅幫助學生掌握語言知識,培養(yǎng)語言能力,同時讓其了解新聞工作的重要性,培養(yǎng)起社會智能感。這個單元分為六個課時,它的教學目標是這樣的:語言目標是掌握詞匯表中的常用單詞和短語,掌握倒裝句的一些基本用法。 技能目標是能初步掌握約會的基本句型并在真實的場景下正確運用。新聞報道類文章的寫作技能。采訪的基本規(guī)范和溝通技能。情感目標是對新聞報道的客觀性和真實性有更好的理解。對新聞記者的職業(yè)有更深入的了解,并能體會其工作的重要性。下面我們來介紹一下第一課時的授課方式,第一課的教學目標是這樣的第一課時的教學目標語言目標:單詞:Occupation, journalist, editor, photographer, curious, personality, enthusiasm
